Coreopsis plant named ‘Docorgranmoons’

ABSTRACT

A new and distinct cultivar of Coreopsis plant named ‘Docorgranmoons’, characterized by its upright and mounded plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; freely flowering habit with numerous inflorescences per plant; double-type inflorescences with yellow orange-colored ray florets; and good garden performance.

Botanical designation: Coreopsis grandiflora.

Cultivar denomination: ‘SWEET MARMALADE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Coreopsis plant, botanically known as Coreopsis grandiflora, and hereinafter referred to by the name ‘Docorgranmoons’.

The new Coreopsis plant is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program is to create uniform Coreopsis plants with numerous double-type inflorescences.

The new Coreopsis plant originated from a self-pollination made by the Inventor in Aalsmeer, The Netherlands in July, 2013 of a proprietary selection of Coreopsis grandiflora identified as code number CP-0010, not patented. The new Coreopsis plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination in a controlled environment in Aalsmeer in July, 2014.

Asexual reproduction of the new Coreopsis plant by vegetative cuttings in a controlled environment in Aalsmeer, The Netherlands since February, 2015 has shown that the unique features of this new Coreopsis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Coreopsis have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Docorgranmoons’. These characteristics in combination distinguish ‘Docorgranmoons’ as a new and distinct cultivar of Coreopsis plant:

-   -   1. Upright and mounded plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Dark green-colored leaves.     -   5. Freely flowering habit with numerous inflorescences per         plant.     -   6. Double-type inflorescences with yellow orange-colored ray         florets.     -   7. Good garden performance.

Plants of the new Coreopsis differ from plants of the parent selection in the following characteristics:

-   -   1. Plants of the new Coreopsis are more compact than plants of         the parent selection.     -   2. Inflorescences of plants of the new Coreopsis have more ray         florets than inflorescences of plants of the parent selection.

Plants of the new Coreopsis can be compared to Coreopsis grandiflora ‘Decoreo16’, disclosed in U.S. Plant Pat. No. 25,241. Plants of the new Coreopsis differ from plants of ‘Decoreo16’ in the following characteristics:

-   -   1. Plants of the new Coreopsis are taller than plants of         ‘Decoreo16’.     -   2. Plants of the new Coreopsis are more freely branching than         plants of ‘Decoreo16’.     -   3. Plants of the new Coreopsis have larger inflorescences than         plants of ‘Decoreo16’.     -   4. Inflorescences of plants of the new Coreopsis have larger,         but fewer, ray florets than inflorescences of plants of         ‘Decoreo16’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Coreopsis plant. The photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Coreopsis plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Docorgranmoons’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 13-cm containers in Aalsmeer, The Netherlands during the summer in an outdoor nursery and under conditions and cultural practices which approximate those generally used in commercial Coreopsis plant production. During the production of the plants, day temperatures averaged 22° C. and night temperatures averaged 17° C. Plants were pinched one time one week after planting and were four months old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used. Measurements represent averages for typical flowering plants.
